hi I need to divide two 10 bit numbers.I would like to know if any kind of chip is readily available or what would be the best circuit for implementing this(A circuit for a higher number of bits like 16 will also do).Any help in this regard would be appreciated.
If the ouptut is obtained by around 500ms it is good enough.I dont want to use a microcontroller or anything because i feel that it would be an overkill.Also the quotient is good enough for me. Thanks Rangan snipped-for-privacy@gmail.com
So 20 input pins and 10 output pins? With pwr and gnd, 32 pins at least. An Atmel AT89S51-24 is $1.89 in ones, they have hundreds in stock right now. I believe it has enough pins, 40DIP, 44TQFP, 44PLCC all available, an internal oscillator so all you need is Vcc and gnd,
32 I/O for a control line and status line plus the required data paths, and way too much code space and ram for your needs. Easily can do the divide for you in the required time.
You will be hard pressed for cheaper or fewer parts or better availability in small numbers and all digital.
Digikey is where I was looking, as I posted. I should have noted who it was when I said 'they.' What surprised me about this particular part is that they are asking less than 6 cents/IOpin. That's about half of what I usually expect to see.
Ahhhh.... The good old 8051 family comes to the rescue. My fave ! Where do you get the 89S51 for $1.89 though ? I'm using some 89S52s ? IIRC at the moment on several projects and I pay rather more than that. From Farnell for sure admittedly.
Overkill ? Come-on, a division is not 'that' simple (compared to an AND or OR I mean, it's not _that_ difficult either). A simple 8 bit uC with integrated oscillator will do the trick. That cost very little, all you will need is that single component ! You will need a programmer but you can do one easily with some resitors, a buffer chip and your // port. As suggested, look at the Atmels, they have nice stuff.
I don't know any chip that do the division and building one from other chips, _that_ is overkill.
